GENESIS 2 was a tournament held by Sidefx and the crew DBR in July 2011, featuring Super Smash Bros. Melee and Super Smash Bros. Brawl singles and doubles as main events, as well as smaller Super Smash Bros. and Project M singles side events. It was the successor of the first GENESIS. Held in Antioch, California and sponsored by Red Bull and SABERGAMING, the tournament had one of the most entrants and prize money ever seen at a tourney, with over 300 attendants and $22,000 in prize money.

A notorious incident of theft occurred at this tournament, committed by renowned smasher and Death By Rape crew member Zelgadis. After most of the crew members had left the hotel room for the day on Sunday, July 17th, Zelgadis returned to the room with his friend Clayton to search for a jacket he had left behind, and then stole an envelope accidentally left on a bed (containing $6,000 in pot bonuses from Sabergaming), returning to Clayton's home to store the money there. After the rest of the crew accused Zelgadis of stealing the envelope when they found it was missing, Zelgadis reportedly lied to them, repeatedly saying that he had not stolen the envelope. After police involvement and almost four hours of investigation, Zelgadis admitted that he had stolen the envelope, and all of the cash was returned. The incident severely damaged Zelgadis's reputation, as well as the reputations of DBR and the Smash community as a whole.

Controller mods of any kind (short hop mod, L-trigger mod, etc), except for cosmetic changes (paint job, different colored plastic), are banned. Those caught with a modded controller are disqualified without a refund.

Turbo or programmed buttons of any kind are banned.

In the event of a match going to Sudden Death, the winner will be determined by percentage. If the above is tied, a rematch will be held.

There is a ledge grab limit of 35 for Meta Knight and 50 for all other characters. If a game goes to time and one player goes over the ledge grab limit for their character, they will automatically lose the game. If both players exceed their ledge grab limit, then this rule is ignored.

The act of stalling is banned.

If time runs out, the winner of the match will be the one called out by the game. If it goes to Sudden Death, then it is determined by percentage. If the percentage and/or both players die at the same time as a result of a suicide move, a one stock 3 minute tie break match is held. Ledge grab limits are reduced to 13 for Meta Knight and 18 for all other characters.

Due to the lack of crews from region specific areas, crew battles for both Melee and Brawl were extended to West Coast vs East Coast. West Coast ended up winning both crew battles, with Gnes KO'ing Atomsk in the Brawl match and Mango taking out Dr. PeePee in the Melee match.
